The core elements (6, 7) have a solid profile. The core elements (6) of two plastic tubes (1, 3) located opposite one another in the tube bundle are guided parallel to one another in the tube bundle and are arranged side-by-side. The core elements (7) of the two other plastic tubes (1, 4) run orthogonally with respect to the side- by-side core elements (6) in the tube bundle. <IMAGE>

Description

Die Erfindung bezieht sich gattungsgemäß auf ein Rohraggregat für die Aufnahme von Kabeln, bestehend aus vier stranggepreßten Kunststoff­rohren, die durch angeformte Filmscharniere in Form von Abstandsstegen vereinigt und zu einem Rohrbündel zusammenlegbar sind, wobei die ein­zelnen Kunststoffrohre bündelzentrumsseitig angeformte Kernelemente aufweisen, die im Rohrbündel aneinander anliegen. Die Kunststoffrohre und die angeformten Filmscharniere sowie damit das Rohraggregat ins­gesamt sind durch Strangpressen, nämlich durch Extrudieren, herge­stellt. - Ein aus einem solchen Rohraggregat zusammengelegtes Rohr­bündel kann unmittelbar erdverlegt, aber auch in ein Schutzrohr ein­gezogen werden. Die Kabel sind z. B. Postkabel oder auch Enegiekabel.The invention relates generically to a pipe unit for receiving cables, consisting of four extruded plastic pipes, which are joined together by molded-on film hinges in the form of spacer webs and can be folded together to form a pipe bundle, the individual plastic pipes having core elements formed on the bundle center side, which abut one another in the pipe bundle . The plastic tubes and the molded film hinges, and thus the tube assembly as a whole, are manufactured by extrusion, namely by extrusion. - A tube bundle folded from such a tube assembly can be buried directly, but can also be drawn into a protective tube. The cables are e.g. B. Post cable or energy cable.

Bei dem bekannten gattungsgemäßen Rohraggregat (DE 35 40 690, DE 35 40 691) sind die Kernelemente an die zugeordneten Kunststoffrohre angeformte, im Querschnitt im wesentlichen dreieckförmige Hohlprofile. Das hat sich bewährt, ist jedoch fertigungstechnisch aufwendig, weil die Hohlprofile mit besonderen Hilfsmitteln kalibriert werden müssen, wenn anders sie bereichsweise zusammenfallen und/oder den runden Querschnitt des zugeordneten Kunststoffrohres beeinträchtigen. Im üb­rigen wirken die so geformten Kernelemente in sehr starkem Maße stabi­lisierend auf das Rohrbündel. Das Rohrbündel ist daher verhältnis­mäßig steif, was bei gerader Verlegung erwünscht, bei stark bogen­förmiger Verlegung jedoch häufig weniger erwünscht ist.In the known generic pipe assembly (DE 35 40 690, DE 35 40 691), the core elements are molded onto the associated plastic pipes and are essentially triangular in cross-section. This has proven itself, but is complex in terms of production technology, because the hollow profiles have to be calibrated with special aids if they otherwise collapse in regions and / or impair the round cross-section of the assigned plastic tube. Otherwise, the core elements shaped in this way have a very strong stabilizing effect on the tube bundle. The tube bundle is therefore relatively stiff, which is desirable for straight installation, but is often less desirable for strongly arched installation.

Der Erfindung liegt die Aufgabe zugrunde, ein Rohraggregat des be­schriebenen Aufbaus so einzurichten, daß es auf einfache Weise ge­fertigt werden kann und zu einem Rohrbündel zusammenlegbar ist, welches weniger steif ist als die bekannte Ausführungsform und welches im Bedarfsfall auch bogenförmig, mit verhältnismäßig kleinem Krüm­mungsradius, verlegt werden kann.The invention has for its object to set up a pipe unit of the structure described so that it can be easily manufactured and can be folded into a tube bundle, which is less stiff than the known embodiment and which, if necessary, can also be laid in an arc shape with a relatively small radius of curvature.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Kernelemente massiv ausgeführt sind, daß die Kernelemente von zwei im Rohrbündel gegenüberliegenden Kunststoffrohren im Rohrbündel parallel zueinander geführt sowie nebeneinander angeordnet sind und daß die Kernelemente der beiden weiteren Kunststoffrohre im Rohrbündel orthogonal zu den nebeneinanderliegenden Kernelementen verlaufen. - Das erfindungsge­mäße Rohraggregat kann einfach und ohne Kalibrierungsprobleme ge­fertigt werden, da die Kernelemente nicht mehr Hohlprofile, sondern vielmehr massive Profile oder Vollprofile und vorzugsweise als längs­laufende, beim Strangpressen der Kunststoffrohre und damit des Rohr­aggregates angeformte Stege ausgeführt sind. Die beschriebene Anord­nung reduziert die Steifheit des aus dem Rohraggregat gebildeten Rohr­bündels, welches auch für bogenförmige Verlegung, selbst bei kleinem Krümmungsradius, ausreichend flexibel ist.To achieve this object, the invention teaches that the core elements are solid, that the core elements of two opposite plastic tubes in the tube bundle are parallel to each other and arranged next to each other and that the core elements of the other two plastic tubes in the tube bundle are orthogonal to the adjacent core elements. - The pipe unit according to the invention can be manufactured easily and without calibration problems, since the core elements are no longer hollow profiles, but rather solid profiles or solid profiles and are preferably designed as longitudinal webs which are integrally formed during the extrusion of the plastic pipes and thus of the pipe unit. The arrangement described reduces the rigidity of the tube bundle formed from the tube assembly, which is also sufficiently flexible for curved installation, even with a small radius of curvature.

Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung. Es empfiehlt sich, die Anord­nung so zu treffen, daß die Kernelemente, bezogen auf die zugeordneten Kunststoffrohre, im wesentlichen in radialer Richtung verlaufen. Beson­ders flexibel ist das Rohrbündel, wenn die nebeneinanderliegenden Kern­elemente im geraden Rohrbündel mit Ausgleichsspalt nebeneinander liegen und wenn die nebeneinanderliegenden Kernelemente außerdem im Rohrbündel eine Länge aufweisen, die kleiner ist als der Abstand der gegenüberliegenden Kunststoffrohre. Die im Rohrbündel orthogonal zu den nebeneinanderliegenden Kernelementen angeordneten Kernelemente liegen zweckmäßigerweise einander gegenüber. Im allgemeinen wird man die Anordnung so treffen, daß diese Kernelemente mit ihren Stirnflächen an den nebeneinanderliegenden Kernelementen anliegen.In particular, there are several possibilities for further training and design within the scope of the invention. It is recommended that the arrangement be such that the core elements, in relation to the associated plastic pipes, run essentially in the radial direction. The tube bundle is particularly flexible if the adjacent core elements lie side by side in a straight tube bundle with a compensating gap and if the adjacent core elements also have a length in the tube bundle that is smaller than the distance between the opposite plastic tubes. The core elements arranged orthogonally to the adjacent core elements in the tube bundle are expediently opposite one another. In general, the arrangement will be such that these core elements rest with their end faces on the adjacent core elements.

Legt man ein erfindungsgemäßes Rohraggregat zu einem Rohrbündel zusammen, so kann das Rohrbündel in dieser Form auf verschiedene Weise fixiert werden, beispielsweise durch Umreifung. Die Umreifung kann mit Umreifungsmaschinen angebracht werden und besteht z. B. aus Umreifungsbändern, die längs der Länge des Rohrbündels mit Abstand voneinander angeordnet sind. Insbesondere kann insoweit mit Klebbän­dern aus verstrecktem Kunststoff gearbeitet werden. Eine bevorzugte Ausführungsform der Erfindung zur Fixierung des Rohrbündels ist in Kombination mit den vorstehend beschriebenen Merkmalen dadurch ge­kennzeichnet, daß die Außenrohre des Rohraggregates Verschlußelemente aufweisen, die Formschlußausbildungen in Form von Ausnehmungen und Einrastzungen besitzen, und daß die Formschlußelemente im Rohrbündel vereinigt sind. Die Formschlußelemente können dabei als längslaufende, beim Strangpressen der Kunststoffrohre und damit des Rohraggregates angeformte Stege ausgeführt sein. Die Formschlußausbildungen lassen sich dann auf einfache Weise durch Ausstanzen herstellen. Um sicherzu­stellen, daß beim Zusammenlegen eines erfindungsgemäßen Rohraggrega­tes zum Rohrbündel die Formschlußausbildungen leicht zum Verrasten gebracht werden können, empfiehlt die Erfindung, daß die Verschluß­elemente, einschließlich der Formschlußausbildungen, im Rohrbündel, in der Rohrbündelachse betrachtet, firstförmig verlaufen bzw. firstförmig sich durchfassen. Diese Ausführungsform hat den weiteren Vorteil, daß die Kräfte, die aus elastischer Verformung im Rohrbündel verbleiben und versuchen, das Rohrbündel wieder zu öffnen, ohne weiteres aufge­nommen werden, während darüber hinaus bei Erdverlegung eine Blok­kierung der ineinander eingerasteten Formschlußausbildungen erreicht wird.If a tube assembly according to the invention is put together to form a tube bundle, the tube bundle can be fixed in this form in various ways, for example by strapping. The strapping can be attached with strapping machines and consists e.g. B. from strapping that are spaced apart along the length of the tube bundle. In particular, adhesive tapes made of stretched plastic can be used. A preferred embodiment of the invention for fixing the tube bundle in combination with the features described above is characterized in that the outer tubes of the tube assembly have closure elements which have form-fitting designs in the form of recesses and snap-in tongues, and that the form-locking elements are combined in the tube bundle. The form-fitting elements can be designed as longitudinal webs which are integrally formed during the extrusion of the plastic pipes and thus of the pipe assembly. The form-fitting designs can then be produced in a simple manner by punching out. In order to ensure that when a pipe assembly according to the invention is put together to form a tube bundle, the form-fitting designs can easily be locked, the invention recommends that the closure elements, including the form-fitting formations, in the tube bundle, viewed in the tube bundle axis, run ridge-shaped or ridge-shaped. This embodiment has the further advantage that the forces that remain in the tube bundle due to elastic deformation and attempt to open the tube bundle again are readily absorbed, while in addition, the interlocking interlocking formations are blocked when laid underground.

Die erreichten Vorteile sind darin zu sehen, daß das erfindungsgemäße Rohraggregat auf sehr einfache Weise durch Strangpressen hergestellt werden kann, und zwar einschließlich der Kernelemente und, soweit vor­gesehen, auch der Verschlußelemente. Dabei treten keine Kalibrierungs­probleme auf, und zwar weder in bezug auf die Kernelemente noch in bezug auf die Verschlußelemente noch auf die einzelnen Kunststoffrohre selbst. Gleichzeitig läßt sich die Anordnung der beschriebenen Bauteile des erfindungsgemäßen Rohraggregates und deren Dimensionierung so einrichten, daß das aus dem Rohraggregat zusammengelegte Rohrbündel die Flexibilität aufweist, die zur bogenförmigen Verlegung erwünscht ist, und zwar auch bei bogenförmiger Verlegung mit verhältnismäßig kleinem Krümmungsradius.The advantages achieved can be seen in the fact that the tube assembly according to the invention can be produced in a very simple manner by extrusion, including the core elements and, if provided, also the closure elements. There are no calibration problems, neither in relation to the core elements, nor in relation to the closure elements, nor to the individual plastic pipes themselves. At the same time, the arrangement of the described components of the pipe unit according to the invention and their dimensioning can be set up in such a way that the collapsed from the pipe unit Pipe bundle has the flexibility that is desired for arc-shaped installation, even with arc-shaped installation with a relatively small radius of curvature.

Das in den Figuren dargestellte Rohraggregat ist für die Aufnahme von Kabeln bestimmt. Es besteht aus vier stranggepreßten, d. h. extrudier­ten, Kunststoffrohren 1, 2, 3, 4, die durch angeformte Filmscharniere 5 in Form von Abstandsstegen vereinigt und zu einem Rohrbündel zusam­ menlegbar sind. Die Fig. 1 zeigt ein solches Rohrbündel im zusammen­gelegten Zustand. Aus den Fig. 2 und 3 entnimmt man, daß die einzel­nen Kunststoffrohre 1, 2, 3, 4 bündelzentrumsseitig angeformte Kernele­mente 6, 7 aufweisen, die im Rohrbündel aneinander anliegen.The pipe unit shown in the figures is intended for the reception of cables. It consists of four extruded, ie extruded, plastic tubes 1, 2, 3, 4, which are joined together by molded-on film hinges 5 in the form of spacer webs and combined to form a tube bundle are measurable. Fig. 1 shows such a tube bundle in the folded state. From FIGS. 2 and 3 it can be seen that the individual plastic tubes 1, 2, 3, 4 have core elements 6, 7 formed on the bundle center side, which abut one another in the tube bundle.

Die Kernelemente 6, 7 sind als massive Profile, d. h. als Vollprofile, ausgeführt. Die Anordnung ist so getroffen, daß die Kernelemente 6 von zwei im Rohrbündel gegenüberliegenden Kunststoffrohren 1, 3 im Rohr­bündel parallel zueinander geführt sowie nebeneinander angeordnet sind. Die Anordnung ist fernerhin so getroffen, daß die Kernelemente 7 der beiden weiteren Kunststoffrohre 2, 4 im Rohrbündel orthogonal zu den nebeneinanderliegenden Kernelementen 6 verlaufen. Die Kernelemente 6, 7 sind im Ausführungsbeispiel und nach bevorzugter Ausführungs­form der Erfindung als längslaufende, beim Strangpressen der Kunst­stoffrohre 1, 2, 3, 4 angeformte Stege ausgeführt. Sie verlaufen, bezogen auf ihre zugeordneten Kunststoffrohre 1, 2, 3, 4, im wesentlichen in radialer Richtung. Damit das Rohrbündel flexibel ist, ist der in Fig. 1 erkennbare Ausgleichsspalt S zwischen den nebeneinanderliegenden Kern­elementen 6 verwirklicht. Er verschwindet, wenn das Rohrbündel bogen­förmig verlegt wird. Man entnimmt aus der Fig. 1 fernerhin, daß die nebeneinanderliegenden Kernelemente 6 im Rohrbündel eine Länge 1 auf­weisen, die kleiner ist als der Abstand a der gegenüberliegenden Kunst­stoffrohre 1, 3.The core elements 6, 7 are solid profiles, i.e. H. as full profiles. The arrangement is such that the core elements 6 of two plastic tubes 1, 3 lying opposite one another in the tube bundle are guided parallel to one another in the tube bundle and are arranged next to one another. The arrangement is also such that the core elements 7 of the two further plastic tubes 2, 4 are orthogonal to the adjacent core elements 6 in the tube bundle. In the exemplary embodiment and according to a preferred embodiment of the invention, the core elements 6, 7 are designed as longitudinal webs which are integrally formed during the extrusion of the plastic tubes 1, 2, 3, 4. Based on their assigned plastic pipes 1, 2, 3, 4, they run essentially in the radial direction. So that the tube bundle is flexible, the compensating gap S recognizable in FIG. 1 between the adjacent core elements 6 is realized. It disappears when the tube bundle is laid in an arc. It can also be seen from FIG. 1 that the adjacent core elements 6 in the tube bundle have a length 1 that is smaller than the distance a between the opposite plastic tubes 1, 3.

Die im Rohrbündel orthogonal zu den nebeneinanderliegenden Kernele­menten 6 angeordneten Kernelemente 7 liegen im Ausführungsbeispiel und vorzugsweise einander gegenüber. Sie liegen mit ihren Stirnflächen an den im Rohrbündel nebeneinanderliegenden Kernelementen 6 an.The core elements 7 arranged in the tube bundle orthogonal to the adjacent core elements 6 lie in the exemplary embodiment and preferably opposite one another. They rest with their end faces on the core elements 6 lying next to one another in the tube bundle.

Im Ausführungsbeispiel sind die Außenrohre 1, 4 des Rohraggregates mit Verschlußelementen 8 versehen, die Formschlußausbildungen in Form von Ausnehmungen 9 und Einrastzungen 10 aufweisen. Dazu wird insbe­ sondere auf die Fig. 3 verwiesen. Im übrigen sind die Formschlußele­mente 9, 10 im Rohrbündel vereinigt. Auch die Verschlußelemente 8 sind als durchlaufende, beim Strangpressen der Kunststoffrohre 1, 4 ange­formte Stege ausgeführt. Die Fig. 1 macht deutlich, daß die Verschluß­elemente 8, einschließlich der Formschlußausbildungen 9, 10 im Rohr­bündel, in der Rohrbündelachse betrachtet, firstförmig verlaufen bzw. firstförmig sich durchfassen, und zwar mit einem Firstwinkel α , der praktisch ein rechter Winkel ist. Insoweit wird auf die in Fig. 1 strich­punktiert eingezeichneten Mittellinien der Verschlußelemente 8 und den eingetragenen Winkel α verwiesen. Aus der Fig. 2 entnimmt man, daß die Verschlußelemente 8 parallel zu dem durchlaufenden Durchmesser, in dem die Filmscharniere 5 liegen, versetzt sind. Das erleichtert die Handhabung beim Schließen des Rohrbündels mit Hilfe der Formschluß­ausbildungen 9, 10. - Es versteht sich, daß die Kunststoffrohre 1, 2, 3, 4 auch mit unterschiedlichem Durchmesser ausgeführt werden können.In the exemplary embodiment, the outer tubes 1, 4 of the tube assembly are provided with closure elements 8, which have form-fitting designs in the form of recesses 9 and latching tongues 10. In particular referred specifically to FIG. 3. Otherwise, the positive locking elements 9, 10 are combined in the tube bundle. The closure elements 8 are also designed as continuous webs which are integrally formed during the extrusion of the plastic pipes 1, 4. Fig. 1 makes it clear that the closure elements 8, including the form-fitting formations 9, 10 in the tube bundle, viewed in the tube bundle axis, run ridge-shaped or ridge-shaped, with a ridge angle α, which is practically a right angle. In this respect, reference is made to the center lines of the closure elements 8 and the entered angle α in FIG. 1. From Fig. 2 it can be seen that the closure elements 8 are offset parallel to the continuous diameter in which the film hinges 5 lie. This facilitates handling when closing the tube bundle with the aid of the form-fitting designs 9, 10. It goes without saying that the plastic tubes 1, 2, 3, 4 can also be designed with different diameters.

Die Verschlußelemente 8 und die Kernelemente 6, 7 werden beim Extru­dieren fortlaufend angeformt. Sie können schon bei der Fertigung oder danach in Längsrichtung bereichsweise ausgestanzt werden. Auf diese Weise kann die Flexibilität des Rohrbündels vergrößert werden, und zwar so weit, daß das Rohrbündel, wie ein Kabel, für Versand- und Verlegezwecke aufgetrommelt werden kann.The closure elements 8 and the core elements 6, 7 are continuously molded during extrusion. They can be punched out in sections in the longitudinal direction during manufacture or afterwards. In this way, the flexibility of the tube bundle can be increased, to the extent that the tube bundle, such as a cable, can be reeled on for shipping and laying purposes.
